Abstract Background The BLOC1S2 gene encodes the multifunctional protein BLOS2, a shared subunit of two lysosomal trafficking complexes: i) biogenesis of lysosome-related organelles complex-1 and i) BLOC-1-related complex. In our previous study, we identified an intriguing unreported transcript of the BLOC1S2 gene that has a novel exon derived from two transposable elements (TEs), MIR and AluSp. To investigate the evolutionary footprint and molecular mechanism of action of this transcript, we performed PCR and RT-PCR experiments and sequencing analyses using genomic DNA and RNA samples from humans and various non-human primates. Results The results showed that the MIR element had integrated into the genome of our common ancestor, specifically in the BLOC1S2 gene region, before the radiation of all primate lineages and that the AluSp element had integrated into the genome of our common ancestor, fortunately in the middle of the MIR sequences, after the divergence of Old World monkeys and New World monkeys. The combined MIR and AluSp sequences provide a 3′ splice site (AG) and 5′ splice site (GT), respectively, and generate the Old World monkey-specific transcripts. Moreover, branch point sequences for the intron removal process are provided by the MIR and AluSp combination. Conclusions We show for the first time that sequential integration into the same location and sequence divergence events of two different TEs generated lineage-specific transcripts through sequence collaboration during primate evolution.

Abstract Herein we present the pathological findings of different tuberculosis stages in Old and New World monkeys kept under human care in Rio de Janeiro, Brazil and naturally infected with Mycobacterium tuberculosis Complex. Fifteen nonhuman primates from five different colonies were incorporated into the study. There are 60% (9/15) Old World Monkeys and 40% (6/15) New World Monkeys. According to the gross and histopathologic findings, the lesions in nonhuman primates of this study are classified into the chronic-active, extrapulmonary, early-activation or latent-reactivation tuberculosis stage. Among the Old World Monkey, 66.7% (6/9) of nonhuman primates, all rhesus monkeys (Macaca mulatta), showed severe granulomatous pneumonia. In all Old World Monkeys cases, typical granulomas were seen in at least one organ regardless of the stage of the disease. In the New World Monkeys, the typical pulmonary granulomas were seen in 16.7% (1/6) of the cases, just in the latent-reactivation stage in Uta Hick’s Bearded Saki (Chiropotes utahickae). In this study, 66.7% (6/9) of Old World Monkeys (OWM) and 83.3% (5/6) of New World Monkeys (NWM) showed pulmonary changes at the histological evaluation. The tuberculosis diagnosis in the nonhuman primates in this study was based on pathological, immunohistochemical, molecular, and bacteriological culture. Although the typical presentation was observed in some cases, the absence of pulmonary granuloma did not exclude the tuberculosis occurrence in nonhuman primates of the Old and New World. Tuberculosis should be included as a cause of interstitial pneumonia with foamy macrophages infiltration in the New World nonhuman primates. Due to the high sensitivity of immunohistochemistry with Anti-Mycobacterium tuberculosis, we suggest the addition of this technique as a diagnostic tool of tuberculosis in the nonhuman primates even when the typical changes are not seen.

ABSTRACTThe ability to extract the direction of the other’s gaze allows us to shift our attention to an object of interest to the other and to establish joint attention. By mapping one’s own expectations, desires and intentions on the object of joint attention, humans develop a Theory of (the other’s) Mind (TOM), a functional sequence possibly disrupted in autism. Although old world monkeys probably do not possess a TOM, they follow the other’s gaze and they establish joint attention. Gaze following of both humans and old world monkeys fulfills Fodor’s criteria of a domain specific function and is orchestrated by very similar cortical architectures, strongly suggesting homology. Also new world monkeys, a primate suborder that split from the old world monkey line about 35 million years ago, have complex social structures. One member of this group, the common marmoset (Callithrix jacchus), has received increasing interest as a potential model in studies of normal and disturbed human social cognition. Marmosets are known to follow human head-gaze. However, the question is if they use gaze following to establish joint attention with conspecifics. Here we show that this is indeed the case. In a free choice task, head-restrained marmosets prefer objects gazed at by a conspecific and, moreover, they exhibit considerably shorter choice reaction times for the same objects. These findings support the assumption of an evolutionary old domain specific faculty shared within the primate order and they underline the potential value of marmosets in studies of normal and disturbed joint attention.HIGHLIGHTSCommon marmosets follow the head gaze of conspecifics in order to establish joint attention.Brief exposures to head gaze are sufficient to reallocate an animal’s attention.The tendency to follow the other’s gaze competes with the attractional binding of the conspecific’s face

AbstractThe pandemic outbreak and rapid worldwide spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not only a threat for humans, but potentially also for many animals. Research has revealed that SARS-CoV-2 and other coronaviruses have been transmitted from animals to humans and vice versa, and across animal species, and hence, attracted public attention concerning host-virus interactions and transmission ways. Non-human primates (NHPs), as our evolutionary closest relatives, are susceptible to human viruses, and a number of pathogens are known to circulate between humans and NHPs. Here we generated global statistics of virus infection in NHPs (VI-NHPs). In total, 121 NHP species from 14 families have been reported to be infected by 139 DNA and RNA viruses from 23 virus families; 74.8 percent of viruses in NHPs have also been found in humans, indicative of the high potential for cross species transmission of these viruses. The top ten NHP species with high centrality in the NHP-virus network are two apes (Pan troglodytes, Pongo pygmaeus), seven Old World monkeys (Macaca mulatta, M. fascicularis, Papio cynocephalus, Lophocebus albigena, Chlorocebus aethiops, Cercopithecus ascanius, C. nictitans) and a lemur (Propithecus diadema). Besides apes, there is a high risk of virus circulation between humans and Old World monkeys, given the wide distribution of many Old World monkey species and their frequent contact with humans. We suggest epidemiological investigations in NHPs, specifically in Old World monkeys with close contact to humans, and other effective measures to prevent this potential circular transmission.

Microspectrophotometric measurements of retinal receptors are reported for eight species of Old World monkey. Although the animals vary greatly in size, colourings and habitat, they all appear to be trichromats and the peak sensitivities of their cones invariably lie near 430, 535 and 565 nm. This consistent pattern contrasts with the results reported earlier for New World monkeys and with the results reported here for Tupaia glis. The trichromacy of frugivorous catarrhine monkeys may have co-evolved with a particular class of coloured fruit. Short-wave cones were rare in all species. The ratio of the numbers of middle-wave and long-wave cones varied between individual animals, but had an overall value close to unity. In the case of all the species examined here, we have recorded a photostable pigment in the inner segments of rods and cones. The latter pigment has a peak sensitivity close to 420 nm and an absorbance spectrum that is narrower than that of a photosensitive visual pigment.

ABSTRACT TRIM5α has been shown to be a major postentry determinant of the host range for gammaretroviruses and lentiviruses and, more recently, spumaviruses. However, the restrictive potential of TRIM5α against other retroviruses has been largely unexplored. We sought to determine whether or not Mason-Pfizer monkey virus (M-PMV), a prototype betaretrovirus isolated from rhesus macaques, was sensitive to restriction by TRIM5α. Cell lines from both Old World and New World primate species were screened for their susceptibility to infection by vesicular stomatitis virus G protein pseudotyped M-PMV. All of the cell lines tested that were established from Old World primates were found to be susceptible to M-PMV infection. However, fibroblasts established from three New World monkey species specifically resisted infection by this virus. Exogenously expressing TRIM5α from either tamarin or squirrel monkeys in permissive cell lines resulted in a block to M-PMV infection. Restriction in the resistant cell line of spider monkey origin was determined to occur at a postentry stage. However, spider monkey TRIM5α expression in permissive cells failed to restrict M-PMV infection, and interference with endogenous TRIM5α in the spider monkey fibroblasts failed to relieve the block to infectivity. Our results demonstrate that TRIM5α specificity extends to betaretroviruses and suggest that New World monkeys have evolved additional mechanisms to restrict the infection of at least one primate betaretrovirus.

ABSTRACT A monospecific antiserum against human corticosteroid binding globulin (hCBG) has been used to identify structural similarities between hCBG and CBG in the blood of other primates and representative species of different vertebrate classes. Double immunodiffusion analysis indicated that only CBG in Old World monkeys and apes cross-react with the hCBG antiserum. This was confirmed by a solid-phase radioimmunoassay for hCBG which also demonstrated that CBG in apes is immunologically identical to hCBG and that Old World monkey CBG comprises most, but not all, of the hCBG epitopes. The electrophoretic mobilities of human, gorilla and gibbon CBG were similar (RF 0·50–0·51), but differed from Old World monkey CBG (RF 0·44–0·49) and chimpanzee CBG (RF 0·47). Although serum/plasma cortisol binding capacities were similar in Old World primates, the dissociation half-times (t½) of cortisol were higher from human and ape CBG (18–25 min) than from Old World monkey CBG (14–18 min). The steroid binding specificities of human and ape (CBG corticosterone > cortisol > progesterone ≥ testosterone) were also different from those of Old World monkey CBG (corticosterone >> cortisol ≃ progesterone > testosterone). Lemur plasma cortisol binding capacity and CBG dissociation t½ of cortisol were similar to hCBG, but its steroid binding specificity was different (cortisol > corticosterone > progesterone ≥ testosterone) and it did not cross-react with the hCBG antiserum. We could not detect high affinity cortisol binding activity in blood samples from New World monkeys, and they did not cross-react with the hCBG antiserum. These results suggest that considerable modification in the steroid binding activity and structure of CBG has occurred since the evolutionary appearance of the primates, but that the rate of change decreased after the cladogenesis of Catarrhine primates.

Abstract. Studies on the distribution of α-galactosyl epitopes with the structure Galα1→3Galβ1→4GlcNac-R on mammalian thyroid cell membranes are of interest, since a natural antibody interacting with this carbohydrate antigen (i.e. the natural anti α-galactosyl IgG antibody) was found to increase in its titre in patients with autoimmune thyroid disorders. By using a radioimmunoassay for quantification of the α-galactosyl epitope, we found variable concentrations of this epitope on thyroid cell membranes of all nonprimate mammals and New World monkeys studied, but not in Old World monkeys and human thyroid. The absence of the identifiable α-galactosyl epitopes on human and Old World monkey thyroid cells correlates with diminished activity of the enzyme, α1-3 galactosyltransferase, which, in other species, synthesizes the α-galactosyl epitopes within the Golgi apparatus. It is argued that a proportion of anti-thyroid reactivity in human normal and pathologic sera, when assayed with mammalian thyroid cells, may be attributed to natural anti α-galactosyl IgG antibody, which interacts with α-galactosyl epitopes on thyroid tissues used for the bioassay.

While regular allomaternal nursing (suckling) has been documented in a number of rodent and carnivore species, as well as in some prosimians, New World monkeys, and humans, it is not common in Old World monkeys and apes. Here, we present a detailed field study of allomaternal nursing in golden snub-nosed monkeys (Rhinopithecus roxellana, Colobinae). We found that more than 87% of infants were nursed by females other than their mothers. Allomaternal nursing was largely confined to the first 3 months of an infant’s life and occurred predominantly between related females who nursed each other’s offspring in a reciprocal manner. Allomaternal nursing enhanced infant survivorship and did not have a negative impact on the future reproductive success of allonursers. Our findings expand the taxonomic distribution of allomaternal nursing and provide fresh insight into the possible factors driving evolution of allomaternal nursing behavior in primates, including humans.

The aim of this research was to compare the photopic and scotopic spectral sensitivity of 2 New World monkeys which have not been previously studied ( Cebus Capucinus and Lagothrix) with that of a normal trichromatic and a protanopic human S and an Old World monkey ( Macaca mulatta). Spectral sensitivity was measured at different wavelengths using a modified method of limits. The results showed that the spectral sensitivity was identical for all Ss at a scotopic level. At the photopic level the normal human S and the Old World monkey also had a similar sensitivity. Both New World monkeys had a marked deficiency in the long wavelength part of the spectrum. This deficiency was comparable to that of the human protan. These results added therefore further evidence that New World monkeys are red deficient.
